Abstract (en)
[origin: WO2011117475A1] A method of treating tall oil pitch, which comprises sterol esters of fatty acids. According to the present invention, the esters of sterols and fatty acids are broken down, in which case especially formic acid esters or acetic acid esters of sterols are formed instead. The free fatty acids and sterol esters generated are distilled or separated in another way. Use of the present invention increases the yield of fatty acids and also facilitates the separation of sterols from tall oil pitch.
